This question might sound weird, but I am currently using a free app for another word processing program and am somewhat annoyed at the way my iPad saves edited documents with it. Instead of updating the original, it creates a copy and saves that. How does Pages treat a document edited on an iPad? If it is the same, then I won't be springing for the $9.99 to get Pages (I don't qualify for the freebie - iPad 2 running the latest version of iOS 7.).
